The time-predictable fault models for seismic strong ground motion estimation in Dhaka, Chittagong and Sylhet were established based on the seismic data, existing literatures, and trench investigation in this project. 

The Indian Plate is moving toward north-east with slip rate of 6 cm/year and subducting under Eurasian Plate along Himalaya Arc and subduction zone continuing from off Sumatra.  The shapes of east ward subducting plate boundaries are clearly found on the depth section of epicenter.  Large earthquakes occurred historically along the subduction fault, namely the 1762 earthquake and the 2004 Mw 9.2 off Sumatra earthquake.  Shillong Plateau is located in the north of Bangladesh.  The E-W trending Dauki Fault, which is a reverse one dipping to the north, is distributed on the southern fringe of Shillong Plateau.
